For me, watching television or movies in AR/VR has very little appeal. Usually, I'm watching with other people and turning to them to see their face or reaction to something on screen is important.

The short-term killer app of AR for consumers is probably a lot more mundane. I think things like heads-up displays on a car windshields or motorcycle helmet visor is a likely contender. But that could change if they get rid of the need for goggles. AR contact lenses could be pretty wild and a less anti-social.

There are a lot more opportunities for AR in commercial applications (like surgeons, technicians, etc...).
